Louis is saving money for a car, he invests $1,200 in an account that pays an interest rate of 7.5%. How many years will it take for the account to reach $14,000? Use formula
A= p (1 +r) ^t

33.970041 years

Step-by-step explanation:

A = p(1+r)^t

14,000 = 1,200 (1+0.075)^t

14,000/1,200 = (1.075)^t

log(14,000/1,200) = t log (1.075)

t = log(14,000/1,200) / log(1.075)

 = 33.970041 years

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
